I'm really proud of how well it fits. It took 100+ hours of work. But it was worth it! We won Best Professional Performance for the group and I won Best Professional Costume Construction for my bunny. The real playboy bunny cuff links were a fun touch too.
It's a real corset with a lace-up back and 1/2" solid steel boning. It required 8 fittings. Working with the satin was hard too.

The uniform was a feat of engineering as well. The entire thing velcros up the back for a easy tear-away. It was so much fun and the audience loved it. :) Go hear to see the performance on YouTube: http://www.youtube.com/watch?v=81ysEOlMM6U
The collar and cuffs were butchered from my bf's old tux shirt.

Personal Thoughts:

I love the series and the character. I got cast in the role before I even saw the series because apparently my friends thought I WAS the living embodiment of Haruhi. I don't think I'm *that* crazy but it was still loads of fun. :p
